Document Summary
Large hadron collider: challenge: collision events in lhc (digitized summary of data from particle collisions which happen 40 million times per second) produced 15 petabytes of data. Cern did not have the capacity to process all of the data: solution: created data aggregation system, which was built on. Mongodb (non-schema structure) to provide the ability to search information: cern uses das 24/7. Due to expansions, system was not fast enough. Unable to deliver real-time alerts to manage market and counter party credit positions in the desired timeframe: solution: built a derivatives trade store based on the marklogic. Created digital map overlaid with real time positions of buses. Network where buses are frequently delayed and take action: future: working to integrate data from rain and flood gauges into traffic control, possibility of under road sensor network, turning machine-generated streaming data into valuable business.
